The parametric vector auto regressive technique has been proposed for adaptive beamforming and STAP. In this paper the expected signal to interference plus noise ratio performance of two variants of the algorithm, with and without forwards-backwards averaging, is derived.

In this paper, a new two-step implementation of the GLRT is proposed. A disadvantage of the GLRT detector is that it is more computationally complex than the simple AMF detector. Our two-step implementation of the GLRT significantly reduces the computational load with a negligible loss in detection performance.
